That's a much better answer than I was thinking of, sure 50% of the downvoted/returned to pool rewards go to curators but half go to all other authors who often times aren't big stakeholders. Unless you mean downvoted post rewards go only towards post rewards and none to curators which would be news to me 

Something this person also seems to ignore is that it's mostly larger stakeholders who are mostly affected by the downvotes in terms of Hive amount so his point never really made a lot of sense IMO.
